mlr3spatiotempcv 2.0.0

Breaking

• Rename task cookfarm to cookfarm_mlr3.
  This was done to distinguish the cookfarm task implementation in {mlr3} better from the original cookfarm dataset.
  cookfarm_mlr3 also now comes with all rows of the upstream cookfarm task and not with a random subset as before.
• Rewrite mlr_resampling_spctcv_cstf implementation.
  The method will produce different fold results compared to {mlr3spatiotempcv} <= 1.0.1.
  This is because of a change/fix in the sampling behavior: before, an (unwanted) stratified sampling was done on time and space variables.
  While this matched the upstream implementation in {CAST}, this did not match with the actual theoretical underpinning described in the literature.

Features

• Add support for DataBackendRaster (@be-marc, #191).
• mlr_resampling_spctcv_cstf: a log message returns the column roles from the Task which are used for partitioning
• The help pages for all methods now describe the methods manually rather than importing the upstream documentation of the respective method.
• Task*ST classes now print column roles space and time (if set) (#198)
• autoplot() gains plot_time_var argument for 3D visualizations of mlr_resamplings_sptcv_cstf resamplings with only 'space' used for partitioning (#197)
• Vignette updates

Bugfixes

• All {mlr3spatiotempcv} methods now comply with the {mlr3} man file declaration logic.

Misc

• Escape all examples and tests for non-installed packages.
• The cookfarm_mlr3 task now sets column roles "space" and "time" for variables SOURCEID and Date, respectively.
• Harden CLUTO tests (#182)
• Large update for the "spatiotemporal" section in the mlr3book
